FASTENING-CLIP FOR SHOW-CASES.

Application filed March 3, 1917.

To all whom it may concern:

Be it known that I, HARRY R. RUsE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Fastening-Clips for Show-Cases, of which the following is a specification.

This invention relates to an improvement in fastening clips for all-glass show-cases such as are employed at and intermediate the corners of the case for effecting a secure connection between the vertical and top plates.

The principal objects of the invention, briefly stated, are to provide a fastening of exceedingly simple and inexpensive construction which may be easily and quickly applied and whose parts will maintain their predetermined relative positions without the requirement of special locking or retaining means and against all vibrations such as tend to cause the loosening or slippage of the parts of show-case fastenings as ordinarily constructed; and to provide a fastening which does not impose any stresses upon the vertical plates or the top plate in connection with the retention of the latter.

lVith the above objects in view, the invention consists in certain novel features of structure and relation which will be set forth in detail as the description proceeds.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of the front portion of a show-case embodying the fastenings of the present invention;

Fig. 2 is a detail perspective view (with certain parts disassembled) of a corner fastening;

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 1, looking in the direction of the arrow;

Fig. 4: is an'enlarged sectional view on the line 44 of Fig. 1.

Similar characters of reference designate corresponding parts throughoutthe several views.

The present fastening consists essentially of two connected clips, one of which, for engagement with the vertical plate to the show-case, and designated generally as A, has an inverted channel-shape cross-section and consists of a plate 1 provided with depending parallel side walls 2, and the other Specification of Letters Patent.

of which, for engagement with the top plate of the show-case, and designated generally as B, includes a base 3 which is transversely adjustable relatively to the plate 1 and has at its outer end an overhanging hook-like lug 4 which fits over the edge of the top plate of the show-case. The base 3 is arranged to slide transversely of the member 1 and is fitted in alining recesses 5 provided at the upper edges of the walls 2, these recesses preferably being of dovetail form and the base 3 having a conforming dove-tail crosssection. The plate 1 is cut away, as at 6, between the recesses 5, and the base 3 0ccupies the cut-away portion 6 of the plate 1 and is flush with the upper surface of said plate.

According to the present invention, the clip B is adjusted manually into its operative relation to the top plate of the showcase; and for the purpose of retaining said clip in such relation, a screw stem 7 is provided, the outer, or, preferably, both of the walls 2 having threaded openings 8 in which said stem engages and the base 3 having a depending lug 9 located between the side walls 2 in parallel relation thereto and pro vided with a threaded opening 10 alining with the openings 8 and in which said stem also engages, said lug being preferably secured to said base by a threaded post 13 formed at its upper end.

The clips A are fitted upon the vertical plates of the show-case in the well known manner, the said plates having recesses 11 to accommodate the lugs 9; and the clips B, which have been previously fitted to the clips A are positioned at their outward limits in order that the top plate of the showcase may be laid and centered upon the vertical plates. After this, the clips B are moved inward by hand until their hook-like lugs 4 contact with the outer edges of the top plate. Thereupon, the screw stems 7 are threaded through the openings 8 and 10 until their movement is limited by the engagement of their head 12 against the adjacent wall 2 of the clip A, the clips 13 being held immovable during the fitting of the stems 7 in consequence of the engagement of their lugs 4 against the top plate.

The screw stems 7 when engaged in the openings 8 and .10, will hold the clips B with the utmost security in their operative positions relatively to the show-case top plate; and the said screw stems will themselves be securely held by the parts through which they are threaded and will not be affected by the constant vibrations which tend to cause the parts of fastening clips as ordinarily constructed to work loose from or slip relatively to one another.

Important advantages of the invention are that all the steps in connection with the fitting and adjustment of the clips A and B may be performed externally oi the showcase; and that neither clip need exercise any pressure on the glass plates to which it is fitted. As regards the clips B, the mei contact of the lugs i with the show-case top plate will be suflicient for the secure retention of said top plate; and it is altogether unnecessary for the retention of the two clips relatively to one another that such clip B be caused to exercise pressure on the top plate, such as, in certain of the ordinary constructions, is relied upon in the development of a binding efl'ect between the clip elements of the fastening.

The construction of the fastening is the same whether it be applied at a corner or along a straight edge of the show-case. In corner fastenings two of the clips A are joined together at a right angle to provide a continuous right-angular channel in which the upper portions of the adjoining vertical plates are received; and each of the angularly-related clips A has associated with it a clip'B in the manner above described.

I claim as my invention In a fastening for connecting the vertical and top plates of show-cases, a clip to fit upon a verticalplate having a vertical wall provided with a threaded aperture, a clip to secure the top plate comprising a base slidably fitted to the first-named clip and plate engaging means at the outer end of said base, the first-named clip having an opening in which the base of the top plate securing clip is arranged and said base having fixed thereto a depending lug provided with a threaded aperture alining with said first-named aperture, said top plate securing clip being freely manually adjustable transversely of said first-named clip and a screw stem having threaded engagement in both of said threaded apertures, said screw stem serving to securely hold said top plate securing clip in any position to which it may have been manually set previous to the engagement of said stem in the aperture of said lug and said top plate securing clip being held in such position during the fit ting of said stem in consequence of its en gagement with the top plate.

In testimony whereof I have hereunto set my hand in presence of two subscribingwitnesses.
